ADJUSTABLE STANDARD FOR WAGQN-BOL STERS.

SPECIFICATION forming part of Letters Patent No. 237,519, dated February8, 1881.

' Application filed December 20,1880. (ModeL) To all whom it ma/yconcern:

Be it known that I, JOHN GRIER, of Rixford, in the county of McKean andState of Pennsylvania, have invented certain new and useful Improvementsin Bolsters and Standards for Wagons or Sleighs; and I dohereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawing, which forms part of this specification.

My invention relates to an improvement in combined wagon bolsters andstandards; and it consists in a bolster having horizontal guides formedon each of its sides, ,with a standard which is made adjustable back andforth upon the bolster, and which has extensions formed on each edge, soas to catch under and over the guides on the bolster, whereby thestandard can only be removed from t e bolster by sliding it off at oneend, as will be more fully described hereinafter.

The object of my invention is to fasten the standard in place upon thebolster by means of a pin or bolt, which is passed down through the topof the standard into the bolster, and

which is made instantly removable, so that the standard can be adjustedback and forth upon the bolster without the necessity of havin g toremove the usual nuts and bolts which have heretofore been used forfastening devices.

The accompanying drawing represents a perspective of my invention.

A represents an ordinary wagon-bolster, which has a horizontal guide orflange, 0, formed upon or secured to each of its sides. Upon the topedge of this bolster is secured a metallic plate, 1), through whichsuitable holes are made at equal distances apart, and which plate servesto prevent all wear and tear upon the bolster as the standard is movedback and forth. This standard G has a suitable extension, I, projectingdown from each of its edges, and which flanges have horizontal recessesformed in their inner sides for the purpose of fitting over and underthe guides on the bolster, as shown. As these flanges form a. part ofthe standard and catch under these guides it is evident that thestandard cannot be lifted upward off of the bolster, but that thestandard must be slid along to the end of the bolster before it can beremoved. Through the standard, just over the bolster, is made a hole, J,through which a pin or bolt of any kind is passed down into the bolster,so as to hold the standard in place. This pin or bolt is instantlyremovable, and it is only necessary to pull the pin out and then movethe standard along to adjust it into any desired position.

Heretofore standards have been made adjustable back and forth upon thebolster; but they have been held in place by means of bolts which arepassed horizontally through both standard and bolster, and which aretrouble some to adjust; and this I disclaim.

The object of my invention has been to make the standard readilyadjustable back andforth without the use of tools of any kind.

Having thus described my invention, I claim- The combination of thebolster having the horizontal guides or flanges formed upon its sides,with the standard having flanges projecting down over its edges, so asto catch over and under the guides, and a means for fastening thestandard in place, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this16th day of December, 1880.
